ELECTRICAL CHARACTERISTICS
Power Dissipation
Absolute Maximum Ratings
Stresses greater than those listed under
Absolute Maximum Ratings
can cause permanent device
failure. Functionality at or above these limits is not implied. Exposure to absolute maximum ratings
for extended periods can affect device reliability.
Operating Ranges
Operating ranges define those limits over which the functionality of the device is guaranteed by 100
percent production testing. Specifications outside of the 0 to 70
°
C range (
–
40 to 85
°
C) are
guaranteed through characterization and sample-lot testing production devices at the temperature
extremes.
